In the moss Polytrichum commune, the haploid chromosome number is 7. A haploid male gamete fuses with a haploid female gamete to
slavikrds [6]

Answer:

1/128

Explanation:

In a diploid individual, 2ⁿ possible gametes can be produced, where <em>n</em> is the haploid chromosome number.

From those possible gametes,

  • (\frac{1}{2})^n is the number of gametes that will contain maternal chromosomes only
  • (\frac{1}{2})^n is the number of gametes that will contain paternal chromosomes only
  • 1-2(\frac{1}{2})^n is the number of gametes that will contain a combination of both maternal and paternal chromosomes.

The probability that an individual spore will contain a set of chromosomes all of which came from the male gamete will be:

<h2>(\frac{1}{2})^7=\frac{1}{128}</h2>
